Beckhoff ELM3002-0405 | EtherCAT Terminal, 2-channel analog input, voltage

The ELM3002-0405 EtherCAT Terminal combines the high-voltage

measurement of the ELM3002-0205 and the low-voltage

measurement of the ELM3002-0305 in a 2-channel terminal.

This means that an EtherCAT Terminal can simultaneously measure

the total voltage of a cell stack or generator, as well as its current

via a shunt. The synchronous coupling of several terminals – for

the purpose of measuring a 3-phase system, for example – is possible

using distributed clocks.

The measuring range is selected in the CoE, as are the other setting

options such as the filter parameters. Regardless of the signal

configuration, all ELM modules have the same technological properties,

and the ELM3002-0405 with oversampling offers a maximum sampling

rate of 50.000 samples per second and channel.

The terminal is equipped with 4 mm laboratory sockets.

This terminal is also available as a variant with an individual calibration

certificate. (See related products) Extensive documentation is available

from Beckhoff sales, support or measurement@beckhoff.com.

This ELM3xxx series measurement terminal enables efficient

implementation of complex system-integrated data acquisition systems

(DAQ) that place high demands on measurement accuracy and time

synchronization.

Bently Nevada 330500 Velomitor Piezo-velocity Sensor

Description

Bently Nevada™ Velomitor Piezo-velocity Sensors are

designed to measure absolute (relative to free space)

bearing housing, casing, or structural vibration. The 330500 is

a specialized piezoelectric accelerometer that incorporates

embedded integrated electronics in a solid-state design.

Because the 330500 incorporates solid-state electronics and

has no moving parts, it does not suffer from mechanical

degradation and wear, and can be mounted vertically,

horizontally, or at any other angle of orientation

Most common machine malfunctions (unbalance,

misalignment, etc.) occur on the rotor and originate

as an increase (or at least a change) in rotor

vibration. For any individual casing measurement to

be effective for overall machine protection, the

system must continually transmit a significant

amount of rotor vibration to the machine casing, or

mounting location of the transducer.

In addition, be careful to install the accelerometer

transducer on the bearing housing or machine

casing. Improper installation may decrease the

transducer amplitude and frequency response

and/or generate false signals that do not represent

actual vibration. Refer to the appropriate instruction

manuals and Application Notes.

Upon request, Bently Nevada provides engineering

services that can identify the appropriate machine

housing measurements and installation assistance

if needed.

Woodward DPC (P/N 5417-557 / P/N 8445-1024 / P/N 8445-1026) Direct Configuration Cable

The Direct Configuration Cable (DPC) is used to connect a Woodward control

or protection unit, which supports DPC connectivity with a PC or Laptop for

configuration and monitoring purposes.

Usage of the DPC

The connection cable delivered with the DPC must be used between DPC and

the Woodward unit to ensure proper functionality of the unit.

An extension or utilization of different cable types for the connection between

Woodward unit and DPC may result a malfunction of the unit.

This may possibly result in damage to components of the system.

If an extension of the data connection line is required, only the serial cable

(RS-232) between DPC and PC or Laptop may be extended. It is recommended

to use an industry standard cable for this.

For a continuous operation (only possible with units, for which a continuous

operation is explicitly stated in the manual) with the direct configuration cable

DPC (e.g. remote control of the easYgen), it is required to use a DPC with P/N

8445-1024 / P/N 8445-1026 (all revisions) or P/N 5417-557 (Rev. F or higher).

When using an earlier DPC version, problems may occur in continuous operation.

It is recommended to use an industry standard serial (RS-232) cable to connect

the DPC with the PC or Laptop for continuous operation.

The shield connector (6.3mm tab connector) at the DPC (only P/N 8445-1024

/P/N 8445-1026 (all revisions) or P/N 5417-557 (Rev. F or higher)) must be

connected to ground.

Basler Electric 9488800100 AVC Sensing Module

Mounting Hardware

The AVC Sensing Module can be mounted directly on a genset using #10-32 or

equivalent hardware. A lock washer should be used between the screw head and

body of the module. Torque applied when tightening the mounting hardware

should not exceed 25 inch-pounds (2.8 N•m).

CONNECTIONS

All AVC Sensing Module connections are located on the back panel. Sensing voltage

is applied to the lower, six position terminal block. Sensing voltage is supplied to the

voltage regulator from the upper, three-position terminal block. Connections consist

of #6 terminal screws. Each terminal accepts a maximum wire size of 12 AWG (13

mm2). When securing connections, apply no more than 9 in-lb (1 N•m) of torque to

each terminal screw.

Before connecting the module, review the terminal descriptions listed in Table 1 and

the connection diagram of Figure 2. At any given time, only one of the two sets of 

sensing voltage input terminals can be used. Under no circumstance can both the

480 Vac and 600 Vac sensing input terminals be connected to a voltage source.

MAINTENANCE

A periodic inspection of the AVC Sensing Module should be made to ensure that all

connections are clean and tight.

The AVC Sensing Module contains no serviceable parts. If a failure occurs, replacement

of the module is recommended.

Basler Electric AVC Sensing Module provides a convenient and cost-effective method

INTRODUCTION

The AVC Sensing Module provides a convenient and cost-effective method

for expanding the applications where AVC63-12 and AVC125-10 voltage

regulators can be applied. The AVC Sensing Module increases the nominal

sensing voltage of style BX AVC63-12 and AVC125-10 voltage regulators

from 200/240 Vac to 480 Vac or 600 Vac. The AVC Sensing Module is

compatible with nominal sensing frequencies of 50/60 Hz and 400 Hz.

A compact, rugged (potted) case enables the AVC Sensing Module to be

mounted directly on the generator.

Other than making connections during installation, the AVC Sensing Module

requires no adjustment or calibration.

Basler Electric AVC125-10 External Bias Control

External Bias Control

The accessory input enables adjustment of the regulation setpoint through

application of a bias signal from an external device. Any external device that

provides a bias signal within the range of ±3 Vdc may be used. Examples of

external biasing devices include var/power factor controllers, excitation limiters,

and synchronizing/load sharing modules. When the AVC receives a positive voltage

(terminal 2 positive, terminal 3 negative) at the accessory input, the regulation

setpoint decreases. A negative voltage (terminal 2 negative, terminal 3 positive)

at the accessory input increases the regulation setpoint. Figure 9 illustrates

interconnection of the AVC accessory input with an SCP 250 Var/Power Factor

Controller and an EL 200 Minimum/Maximum Excitation Limiter.

When using an external biasing device, ensure that it is configured properly for

use with the AVC63-12 or AVC125-10.

Basler Electric Inrush Current Reduction Module

Options

The AVC63-12 and AVC125-10 may be equipped with the following options to

enhance operation.

Remote Voltage Adjust

Connect a 10 kΩ, 2 W potentiometer across terminals 6a and 7. remove the

jumper from terminals 4 and 7. and adjust the front panel VLT ADJ control fully

clockwise to enable remote adjustment of the voltage setpoint.

Inrush Current Reduction Module

A Basler ICRM-15 is required when energizing the AVC63-12 or AVC125-10 from

a source that is already at the regulator input power rating.

The ICRM-15 minimizes the amount of inrush current that could be seen when

power is applied.

Excitation Disable

This option disables excitation by removing power from the regulator. A switch

removing voltage from terminals 26. 28 and/or 30 will remove regulator power.

Excitation Limiter

The Basler EL 200 provides an initial, fast-acting limit of the field current at a

user-defined level. Once the field current has changed to the selected level, the

EL 200 provides a signal to the regulator to change the excitation level.

Basler Electric Startup and troubleshooting procedures for the AVC63-12

Startup

Startup and troubleshooting procedures for the AVC63-12 and AVC125-10

are listed in the following procedure.

Symptoms of startup problems stemming from improper regulator adjustments

and certain generator system problems that resemble faulty regulation are

listed with possible solutions. Simplifying the system by eliminating components,

such as remote adjustment potentiometers and other nonessential items, can

be helpful in the troubleshooting process. Adjustments, options, and an operational

test are included in the paragraphs following the procedure.

1. Ensure that the regulator has been installed in accordance with the Installation

and Connections paragraphs before proceeding with system startup.

2. Start the prime mover and bring it up to rated speed.

If the voltage does not build up:

a. Flash the field.

b. Remove power for one minute to reset the overexcitation circuit.

3. Slowly adjust the VOLT potentiometer or external, voltage adjust rheostat until

the voltage reaches nominal.

If the voltage will not build up to rated:

Check the generator output for a shorted or excessive load.

4. Apply and remove the generator load to check stability.

If the generator response is too slow or is hunting (oscillating):

a. Check the generator output for a shorted or excessive load. Adjust the STB

potentiometer with no load applied.

b. Check stability of the governor.

5. Check regulation under normal operating conditions.

If the regulation is poor:

a. Check that the prime mover is up to rated speed.

b. Check that the voltmeter is connected at the same point as the regulator

sensing.

c. Use an average-sensing voltmeter (not an rms-sensing voltmeter).

6. Reduce the generator frequency. The generator output should decrease

from this point.

If the generator output voltage does not decrease at the desired frequency:

a. Check that all wiring is in accordance with the connection diagrams provided

in this instruction sheet.
